The worst math problem I have ever had the misfortune to encounter.

Just look at it. The scaling on the chart. The units that don't agree with each other. The size of the whole thing that makes it impossible to accurately guess where the curve lies. No accompanying data to clarify. This is a perfect example of making a very simple problem, designed to teach a simple concept about estimation, into a clusterfucked math enigma. I paid 70 dollars for the privilege of using this fine program. Screw you, webassign. Screw you, textbook companies, and most of all, Fuck You, University Mathematics Department, for forcing student to put up with this shit just so you can save yourself the hassle of creating problems sets of your own and grading them yourselves. Cuntnuggets.
